There are grooves cut into the body of koni yellows which let you select a perch height. Would a machine shop be capable of cutting more grooves as evenly and precisely as the original grooves?

 

I would assume so... You may also be able to accomplish the same thing using a pipe cutter... and some care

 

anyone else know for sure?

its a pretty precise groove. it doesnt look rounded in the groove either. the bottom of the groove is squared off for a precise fit of the ring. i suppose it could be compared to cutting new grooves in pistons for rings.

A decent machine shop can cut anything you want at any angle within .001" in most any material..
